Dynamical Modelling and Simulation of Waste water Filtration Process by Submerged Membrane Bioreactors [PDF]

open access: yes, 2009
A mathematical model was developed for the filtration process and the influence of aeration on Submerged Membrane Bioreactors. The dynamics of sludge attachment to and detachment from the membrane, in relation to the filtration and a strong intermittent ...

Production of highly porous glass-ceramics from metallurgical slag, fly ash and waste glass [PDF]

open access: yesActa Periodica Technologica, 2004
Glass-ceramics composites were produced based on fly-ash obtained from coal power stations, metallurgical slag from ferronickel industry and waste glass from TV monitors, windows and flasks. Using 50% waste flask glass in combination with fly ash and 20%

Aerated bunker discharge of fine dilating powders [PDF]

open access: yes, 1991
The discharge rate of coarse powders (mean particle size 500 ¿m) from bunkers without aeration can be described by both empirical relations and theoretical models. In the case of small particles the discharge rate is largely overestimated.
